Good Critique on Recent Homosexuality Study

I found a great critical review of the amgydala/hemisphere symmetry study I posted about the other day (via The Neurocritic). After providing examples of numerous confounds to the study, the reviewer made this conclusion:

There are many more technical problems with the analytical techniques used in this study. I'm not going to bother going through all of them. Needless to say, this study proves absolutely nothing, and is just another example of bad science. As an MRI researcher, this article offends me personally, for it gives MRI and PET research a bad rap; I'm going to go throw up now.
I would still take this a step further. It's not just the analytical techniques, it's the starting point. We are mired in this search to correlate vague, highly complex variables from two disparate systems - sexuality and the size of a brain region. I know I keep saying this, but it's just phrenology with better tools.

Studies in neuroscience historically run into problems because they try to run before they can walk. While it's amazing to have the technology to measure these brain differences, our understanding of consciousness, personality, character, sexuality, addiction, habitual behavior, etc. is still too questionable and badly defined to make true correlations with neurological attributes. We're nowhere close to close on this one.

The nature of these "neuropsychological" studies is still in dire need of a paradigm shift.

The Fruitless Hunt for the Physical Substrate of Homosexuality

It seems these silly studies comparing brain regions of gay and straight people are surfacing again. Frankly, if I was gay (which I'm not), I'd be offended by these studies. There is still zero definition of actual character traits when studying these people. We're defining "gay" by an attraction to the same sex. So that's it? All "gay" men act like women? Why not just assume all gay men love the The Bird Cage too?

This idea that gay women have masculinized brains and vice versa is a total stereotype and grossly inaccurate. There are exceptions to the rule everywhere - for instance, how do we categorize macho, aggressive male rappers with homophobic lyrics that also...have sex with men! Like with any shoddy study, they just ignore the unwanted data. And don't let that stop the science writers from the absurd extrapolations like the headline from New Scientist - "Gay brains structured like those of the opposite sex."

This claim is based on a study with 45 gay and straight people - not exactly a huge sample size. Not to mention, there's no implication that maybe the difference in amygdala structure may be caused by experience.

This is just another example of dark ages phrenology...I mean, current neuroscience.

In Entertainment News...

Dr. Drew Calls Tom Cruise "mentally ill." I can't say I'm a HUGE Dr. Drew fan, but sometimes he comes out with gems like this:

"A lot of people in the public eye who behave strangely have mental illness we can learn from, and much of it is based on childhood trauma, without a doubt. Take a guy like Tom Cruise. Why would somebody be drawn into a cultish kind of environment like Scientology? To me, that's a function of a very deep emptiness and suggests serious neglect in childhood - maybe some abuse, but mostly neglect."
To a lot, this probably sounds like psychobabble, but from my experience, and based on what I've learned from the few the really good psychiatrists I've met (all one of them) - abuse and neglect are the main culprits for futurepathological behavior. It is NOT chemical imbalances and neurological disorders - that's a pharmaceutical fantasy...

"Brain Downloads" Are Not Going to Happen

Nice to see Neurophilosophy agrees with me on this one. Here's a totally stupid and uninformed article on why "brain downloads 'will make [school] lessons pointless.'"

Just recently, I wrote a post about why this is impossible (in the context of Dr. Daniel Carlat's Wired article on brain scans), it seems the progressive ideas of the Matrix are far too pervasive in our culture.

"I think people will be able to directly access, Matrix-style, all the vocabulary you need for a foreign language, leaving you just to clear up the grammar."
This amazingly asinine quote comes from the guy steering curriculum for 1300 private schools in the UK. Best of luck with that, stupid...



Not quite, Neo...

Fiction Vs Reality?


The boundaries are getting blurred. From Neurocritic, a real live Telekinesis competition hosted by Noxious Sector.

"an ongoing collaborative endeavor by Canadian artists Ted Hiebert, Doug Jarvis and Jackson 2Bears, dedicated to the exploration of alternative cognitive function, the paranormal and the absurd."
Is this just silly performance art, or are these dudes actually trying to move things with their minds? In the misinformation internet age, I really can't tell what's real anymore. Gave me a good chuckle either way.

The Emporer's Clothes Don't Keep Him Warm

Aside from my father who is working on a ground breaking book on psychotherapy and consciousness, this Psychology PhD from Austin, TX, John Breeding is the clearest I've seen about the danger of prescribing pscyhotropic drugs for "bogus, made-up" conditions like ADHD and depression. Pretty ballsy given the current climate of psychiatric treatments. Amen, brother.

CLARIFICATION: After a brief comment dicussion (thanks Adam), I wanted to say that I don't think the symptoms of depression or ADHD aren't real, and that certain drugs can't be helpful in certain, specific instances. What I will say is that the idea behind the mechanism of action for anti-depressants is heavily flawed, and basically unproven. Contrary to popular belief, there is no established baseline for the "normal" levels of the neurotransmitter most anti-depressants are supposedly regulating (serotonin and dopamine).

Most studies say it's barely more effective than placebo. Other reports mention how studies showing their ineffectiveness are often shelved, and even worse, the side effects of many of these drugs can be pretty awful - decreased libido, movement disorders, psychotic behavior, and most bizarrely, the zaps. The over-diagnosis of these conditions and the pursuant over-prescription of frankly experimental psychotropic drugs is a sloppy and irresponsible practice.

Actually, this is all stated better in this clip of Dr. Breeding.
